I stay there quite often.
Your right about the key cards. Your lucky its only the club lounge you cant get access too. Most stays I cant even access my room! i was there this week. 2 occasions i could not get into the lounge and once into my room!
The points never post. The last 7 or 8 stays I have had to email and request.
i just keep an email ready to fire over to PC on the seventh day!
I did get an email back from PC a month ago saying they would contact the hotel as it was an ongoing issue.
